Hi @jramsey123,
I don’t think that updating the dtsi file would work.
You can try to use device tree overlays to update the device tree at runtime.
We do this to deploy PYNQ on the KV260. https://github.com/Xilinx/Kria-PYNQ/tree/main/dts
This thread can also help you trying to define the dtbo for your use case.
